If the appliance is overloaded and
trying to heat a system with a
com ined heat load in excess of
55,000 BTU’s the urner will run for
long continuous periods without a
reak, this will then result in
excessive oven temperatures and
excessive urner temperature.
This will result in overheating of the
fan motor and damage to the
earings.

If there are only a few radiators on
the system, this will cause the urner
to shut down quickly and then the
oven will not reach the desired
temperature.
The underloading pro lem can e
easier to deal with than the
overloaded situation, read the Heat
Balancing section for further info.

Solid Fuel stoves should always
produce good quantities of hot water
ecause the fire runs continuously and
at high temperatures.
This is not the case with converted
appliances and it is therefore
important to make sure that the hot
water side of the system is adequate.
Take care with indirect systems which
have een running for a long time on
solid fuel systems.
Because water temperature control is
not all it should e, many of the
cylinders have een exposed to
excessive and continuous high
temperature calcification in the
indirect coil.
This can result in major post
conversion heat exchange pro lems
and consequent lack of hot water.
If the primary pipe work does not
look adequate, modify it and fit a fully
pumped, three port valve system.
